Pause and resume schemes for gesture-based game

1. A method performed under control of a processor for a gesture-based game system, comprising:

receiving, by the processor, a pause command that indicates pausing play of a gesture-based game;

in response to the receipt of the pause command, capturing, by the processor, a first image of a player currently playing the gesture-based game, the first image being associated with a first posture of the player substantially at the time of the pause command;

generating, by the processor, an outline of the player corresponding to the first image of the player;

pausing, by the processor, the play of the gesture-based game;

capturing, by the processor, a second image of the player, the second image being associated with a second posture of the player, the second posture being at a time subsequent to the time of the pause command;

determining, by the processor, whether the second image of the player substantially matches the outline of the player corresponding to the first image; and

resuming, by the processor, the play of the gesture-based game upon determining that the second image substantially matches the outline of the player corresponding to the first image.

2. The method of claim 1 , further comprising:

displaying, by the processor, on a screen coupled to the gesture-based game system, the generated outline of the player.

3. The method of claim 1 , wherein the generating the outline of the player includes calculating, by the processor, x-y coordinates of the outline of the player.

4. The method of claim 3 , wherein the generating the outline of the player further includes calculating, by the processor, a distance between the player and the gesture-based game system.

5. The method of claim 1 , further comprising:

identifying, by the processor, an avatar image associated with the first image of the player, and

wherein the generating the outline of the player is based, at least in part, on the avatar image.

6. The method of claim 1 , wherein the capturing the second image, the determining and the resuming are performed in response to a processor-issued resume command.

7. The method of claim 1 , wherein the generating the outline of the player includes calculating, by the processor, x-y coordinates of the outline of the player, and

wherein the determining includes comparing, by the processor, the second image of the player with the x-y coordinates of the outline of the player.

8. The method of claim 7 , wherein the generating the outline of the player further includes calculating, by the processor, a distance between the player and the gesture-based game system, and

wherein the determining further includes comparing, by the processor, the distance between the player and the gesture-based game system associated with the first image of the player and a distance between the player and the gesture-based game system associated with the second image of the player.

9. The method of claim 1 , wherein the pause command includes a speech of the player.

10. The method of claim 1 , wherein the pause command includes a gesture of the player.

11. A gesture-based game apparatus, comprising:

an input receiving unit configured to receive a pause command that indicates pausing play of a gesture-based game;

a camera configured to capture a first image of a player currently playing the gesture-based game in response to the receipt of the pause command, the first image being associated with a first posture of the player substantially at the time of the pause command;

an outline generating unit configured to generate an outline of the player

corresponding to the first image of the player;

a control unit configured to pause the play of the gesture-based game in response to the receipt of the pause command,

wherein the camera is further configured to capture a second image of the player, the second image being associated with a second posture of the player at a time subsequent to the time of the pause command; and

a determination unit configured to determine whether the second image of the player substantially matches the outline of the player corresponding to the first image,

wherein the control unit is further configured to resume the play of the gesture-based game upon determining that the second image substantially matches the outline of the player corresponding to the first image.

12. The apparatus of claim 11 , further comprising:

a displaying unit configured to display the generated outline of the player.

13. The apparatus of claim 11 , wherein the outline generating unit is further configured to calculate x-y coordinates of the outline of the player.

14. The apparatus of claim 13 , wherein the outline generating unit is further configured to calculate a distance between the player and the gesture-based game apparatus.

15. The apparatus of claim 14 , further comprising:

a storage unit configured to store at least one of the x-y coordinates of the outline of the player and the distance between the player and the gesture-based game apparatus.

16. The apparatus of claim 11 , further comprising:

an image identifying unit configured to identify an avatar image associated with the first image of the player, and

wherein the outline generating unit generates the outline of the player based, at least in part, on the avatar image.

17. The apparatus of claim 11 , wherein the outline generating unit is further configured to calculate x-y coordinates of the outline of the player, and

wherein the determination unit is further configured to compare the second image of the player with the x-y coordinates of the outline of the player.

18. The apparatus of claim 17 , wherein the outline generating unit is further configured to calculate a distance between the player and the gesture-based game apparatus, and

wherein the determination unit is further configured to compare the distance between the player and the gesture-based game apparatus associated with the first image of the player and a distance between the player and the gesture-based game apparatus associated with the second image of the player.

19. The apparatus of claim 11 , wherein the pause command includes a speech of the player.

20. The apparatus of claim 11 , wherein the pause command includes a gesture of the player.

21. A non-transitory computer-readable storage medium having stored thereon computer-executable instructions that, in response to execution, cause a gesture-based game apparatus to perform operations, comprising:

receiving a pause command that indicates pausing play of a gesture-based game;

in response to the receipt of the pause command,

capturing a first image of a player currently playing the gesture-based game, the first image being associated with a first posture of the player substantially at the time of the pause command;

generating an outline of the player corresponding to the first image of the player;

pausing the play of the gesture-based game;

capturing a second image of the player, the second image being associated with a second posture of the player at a time subsequent to the time of the pause command;

determining whether the second image of the player substantially matches the outline of the player corresponding to the first image; and

resuming the play of the gesture-based game upon determining that the second image substantially matches the outline of the player corresponding to the first image.

22. The non-transitory computer-readable storage medium of claim 21 , the operations further comprising:

identifying an avatar image associated with the first image of the player, and wherein the generating the outline of the player is based, at least in part, on the avatar image.
